java数字转大写程序

你好！以下是一个将Java中的数字转换为大写的示例程序：

import java.util.Scanner;

public class NumberToWords {
    private static final String[] units = {"", "一", "二", "三", "四", "五", "六", "七", "八", "九"};
    private static final String[] tens = {"", "十", "二十", "三十", "四十", "五十", "六十", "七十", "八十", "九十"};
    private static final String[] digits = {"", "百", "千", "万"};

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入一个整数：");
        int number = scanner.nextInt();
        System.out.println(convertNumberToWords(number));
        scanner.close();
    }

    public static String convertNumberToWords(int number) {
        if (number == 0) {
            return "零";
        }
        
        StringBuilder result = new StringBuilder();
        int unitIndex = 0;
        
        do {
            int n = number % 10;
            if (n != 0) {
                result.insert(0, units[n] + digits[unitIndex]);
            }
            unitIndex++;
            number /= 10;
        } while (number > 0);
        
        return result.toString();
    }
}

这个程序会要求用户输入一个整数，并将其转换为大写的中文数字。例如，输入12345，程序会输出"一万二千三百四十五"。希望能对你有所帮助！如果有任何疑问，请随时向我提问。
